TQALL WHOM IT MAY CONCERN:

Be it known that I, W. A. DUNCAN, of Syracuse, in the county of Onondaga, and Stateof New York, have invented certain now and useful improvements in a Hay-Rake and Leader," and that the following description, taken in connection .with the accompanying drawings, hereinafterreferred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements which my inven tion maybe distinguished from all others of a similar class, together with such parts as I claim and desire to i have secured to me by Letters Patent.

The present invention consists, first, in so hanging the ralrethat it cannot dump, and also be susceptible of being adjusted to the various kinds of hay or grain in connection with which it may be used; second, hanging the rake to the machine, so that .it will be drawnoutside of the driving-wheels, thus preventing it from becoming clogged; third; in so hanging in front 'of one or bothof the driving-wheels of the machine a clearer, that, as the machine is drawn over the ground, the hay scattered upon it will be elearedthereby from the track or tracks of the drivingwheels by being either thrown to the outside or inside of such wheels, as may be deemed best, the clearer, when throwing the hay inside of the driving-wheels, serving as a gatberer for the same.

In addition to the above, which compose the principal and most important features and principles of the present invention, I have also made many other minor improvements that, in connection, serve to'secure a-most perfect operation of the same. In the accompanying plate of drawings my improvements in shay-rake and losder are illustrated I Figure 1 being an elevation of the front end of a hay-rake and louder made according to the present invention, and Figure 2 a central longitudinal vertical section taken in the plane of the line z 2:, fig. 1. 7

AA, in the drawings, represent theprincipal or main framework of the machine, "to which the various parts constituting the same are hung orsecured, as will benow explained, the frame being of suitable construction to receive and accommodate the same. At or near therear end of the frame A, and extending across the same from one side to the other,-is hung an axle-shaft, B, so as to freely tum-therein, which axle-shaft projects at .each side of-the frame, and has secured to it at such projecting onds similar driving and traction-wheels, C. To that portion of the axle shaft B embraced between the side pieces D of the frame A, a hollow cylinder or drum, E, is secured, that at each end is closed by heed-plates, and revolves between disks G secured to the frame A, which disks upon their face or side in contact with the heads of the cylinder are each provided with a similar cam groove or way H of the shape showirby dotted lines in fig. 2. In these cam grooves or ways H the ends of a bar or rail, I, play or move, which bar passes through a radial slot,J, made in each end of the hylinder E, and extends the entire length of the cylinder. To and along this bar I a series of bent or curved teeth, K,'is secured. These teeth extend toward the outside of the cylinder through apertures, through which they are made to pass, and thus to project from the cylinder at the proper time in its revolu'tion by the action of the cam grooves or ways II upon the bar'I, when, continuing the rotation, such teeth are draivn bacltinto thewcylinder by the-action of said grooves and again thrown'out, and so on, for purposes to be hereinafter specified. It may be here remarked, before proceeding with the description of the remaining portions of my machine, that it is intended to have a series of the toothed bars I arranged in the cylinder-in a manner similar to that above explained, although in the drawings I have shown but one. Across the rear end of the machine a. draw-bar, J, extends, that at each end is hung by rods K passing'outside of the driving-wheels C to-end upon the hooks L at the outer ends of the cross-bar M of the framework A, which passes in front of the said wheels. To the draw-bar J is hung, through standards N, the rake-bar 0, so as to rest upon the ground, or nearly so, these standards, at their upper ends, being lo'oscly loopedor clasped about the draw-bar. To the rake bar O a series of rake-teeth, P, is secured, which teeth project toward and under the revolving cylinder E in position for raking and gathering up the hay scattered 'upon the ground, as the machine in any suitable manner is drawn overit, the teeth terminating at their inner ends in upward projecting curved arms Q. To prevent the rake from dumping, when it catches in the ground at the point of its teeth, I connect the rake-bar O to the drawbar J in addition to hanging it upon the same by the loop-standards N through rear vertical lever or link-pieces B, that, at theirlower ends, are hung to the projecting arms S of the rake-bar, and at their upper ends to the projecting arms T of the draw-bar. To the main fromcA of the machine, in front of the cylinder E, a. frame, U, is hung at one end so as to swing, which fro-me extends upward in an inclined direction toward the front end of the framework A. At each end of this frame U a. roller, V, is hung, so as to turn, around which rollers, from one to the other, passes an endless apron or belt, W, provided at suitable points of its length with trans erse cleats or strips X. To the outer end'of the upper one of the rollers V a pulley, Y, is'secured, around which passes an endless belt or band, 7i, that, at its opposite end, posses around a pulley, A, secured to thc axle and driving-shaft I? of the machine, by which means the endless apron W is driven as the machine is drawn over the ground. To the under side of the endless apron frame U pnwls I! are secured in position to engage with the teeth or notches a of rock-bar C permanently fixed or'secured to the uprights D" of the framework A, the purpose of which pawls and rocks is to enable the frame U to be more or less inclined in direction, according to the height which it is necessary to have its upper end to accommodate it to the ever-varying height of the hay in the wagon as it is loaded with the same.

The operation of the machine above described is as follows: As it is drawn over the ground upon which the hay to be gathered and loaded in a wagon is scattered, the rn-hc-tecth of the rake-hog gnther and rake up the hay, from which, by the teeth K of the cylinder E, (which teeth then project from the cylinder through the openings a in the some and pass between the rake-teeth,) the hay is then taken and carried up by thorn to the endless apron, to be carried by it to the wagon, the teeth of the cylinder, as they reach the said endless apron with the hay, being drawninto the cylinder, and thus leaving the hay free to be til-ken up by the endless apron, asis manifest without any further explanation. '.l. o clear the holy from the ground in frontof the drivingwhecls of the machine as it passes over the some, I have pieced in front of the wheele sclearervboerdor plate, D, that, by means of extension arms, E, is secured to the framework A, this clearer-board in the present instance being inclined in a direction to throw the hay to the outside of the wheels. In connection with the clearer-board D I have also arronged, just in front or in advance of it, a gatherer-boord,.F, which board,

through a. triangular-shaped frame, G' is hung to the frameworkA in a vertical plane, moving in guide-pieces H of the some, the purpose and object of this gethercr being to gather in the hay upon the ground toward the centre of the machine for being taken up by the revolving rake-toothcylinden The adjusting of the rake to the difl'ercnt kinds of hay or grain in connection with which the machine is to be used can be accomplished by providing a series of hooks at L to receive the ends of the lever or draw-burs K, or by lengthening or shortcuing the connection through the link-pieces bet-ween the draw-bar J and rake-barr o, for which purpose a series of apertures is to he made in such liiik-pieccs.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The rake-bar O, suspended by the standard N from the draw-bur J, hung by the adjustable rolls K on hooks L, in combination with link-pieces R pivoted at one end to the projecting arm-T of the draw-bar J",-nnd at the other end to the projecting arms S of the rnke-bur O, substantially as described for the purpose specified.

2. The clearer-board D attached to the extension arms E and gatherer-bourd If" hung from the triangularfromc G ull secured to the frame A, when arranged to operate together substantially as described for the purpose specified.

The above specification of my invention signed by me this ninth day of July, 1866.
